(Nasdaq: SUPN), a biopharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases, today announced that it expected to file its Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (the “Annual Report”) in the near term. Full Year 2022 Financial Guidance (GAAP) The Company reiterates the full year 2022 financial guidance initially announced on February 28, 2022 as set forth below:  Amount ($ in millions)Total revenues (1)$640 – $680Combined R&D and SG&A expenses$460 – $490Operating earnings (2)$20 – $40Effective tax rate25% – 28%   ___________________________________________(1) Includes net product sales and royalty revenue.(2) Includes amortization of intangible assets and contingent consideration expense (gain). Full Year 2022 Financial Guidance — GAAP to Non-GAAP Adjustments An itemized reconciliation between projected operating earnings on a GAAP basis and projected operating earnings on a non-GAAP basis is as follows:  Amount ($ in millions)Operating earnings – GAAP$20 – $40Adjustments: Amortization of intangible assets$80 – $85Share-based compensation$20 – $25Contingent consideration$8 – $12Depreciation$2 – $3Operating earnings – non-GAAP$130 – $165   Non-GAAP Financial InformationThe Company’s 2022 financial guidance in this press release contains a financial measure, non-GAAP operating earnings, which does not comply with United States generally accepted accounting principles (GAAP). The non-GAAP financial measure should be considered in addition to, not as a substitute for or in isolation from, or superior to measures prepared in accordance with GAAP. Non-GAAP operating earnings adjusts for non-cash share-based compensation expense, depreciation and amortization, and accretion of contingent consideration, and for factors that are unusual or unpredictable, and exclude those costs, expenses, and other specified items presented in the reconciliation tables in this press release. We believe the use of non-GAAP operating earnings measure is useful supplemental information to investors regarding the Company’s results of operations and assists management, analysts, and investors in evaluating the performance of the business. There are limitations associated with the use of non-GAAP financial measure. Including such measure may not be entirely comparable to similarly titled measures used by other companies, may not reflect all items of income and expense, as applicable, that affect our operations, potential differences among calculation methodologies, may differ from the non-GAAP information used by other companies, including peer companies, and therefore comparability may be limited. We mitigate these limitations by reconciling the non-GAAP financial measures to the most comparable GAAP financial measures. Investors are encouraged to review the reconciliation.
